I seem to be getting a different problem with gdbmods: # ./gdbmods kernel.debug.200208211211 vmcore.2 please be patient while loaded modules are resolved gdbmods using kernel: kernel.debug.200208211211 gdbmods using core: vmcore.2 gdb extra arguments: if: Missing file name. # > That means that either your crashdump doesn't match the kernel.debug > you told the script to use, or the kernel you told the script to use > does not have debug symbols. > > If this does not work, or looks too complex, can you please compile > vinum statically into your kernel.

Then "make kernel" and bounce her?
